The Senior Class Project for Comparing two Quantitative Variables would involve the following:

1. Choose two quantitative variables to compare, such as how temperature affects the concentration of a pollutant in a liquid or the effect of time on the growth of plants.

2. Collect and organize data on the two variables, such as a series of temperature measurements and pollutant concentrations, or times and plant heights.

3. Create a graph to show the relationships between the two variables.

4. Draw conclusions from the data. This can be done through an analysis of the graph or by using statistical methods such as linear regression.

5. Present the results in an easily understandable way, such as a presentation, poster, or report.
